Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?

Correct option (d)Acetyl Co-A

Explanation:

Acetyle Co-A is common to respiration mediated breakdown oi fats, carbohydrates and proteins. Glucose and fructose are phosphorylated to give rise to glucose-6-phosphate by the activity of the enzyme hexokinase. Glucose-6-phosphate is then converted into fructose-6-phosphate and further to fructose 1-6-Bisphosphate. Pyruvic acid is the end product of glycolysis.

(c) Acetyl CoA

Explanation:

Acetyl CoA is common to respiration mediated breakdown of fats, carbohydrates and proteins. Fats are broken down to fatty acid and glycerol and again fatty acid degraded to acetyl Co - A . Protein first degraded by proteases to indiviual amino acids which deaminated to pyruric acid and further decarboxylised to acetyl Co- A.
